ABSTRACT: Water used for irrigation can vary greatly in quality depending upon type and quantity of dissolved salts. Irrigation water samples from different farms located in north, south, west and east of Huraimla, Saudi Arabia have been analyzed. Source of all samples is ground water. The present study attempts to bring an awareness among the framers about the quality of ground water for irrigation purposes. The water quality parameters such as pH, electrical conductivity, TDS, total hardness, nitrate and iron were considered. There are differences among water parameters based on their location. The results are compared with standards of FAO. A systematic correlation and regression study showed significant linear relationship among different pairs of water quality parameters. The usefulness of these linear regression equations in predicting the irrigation water quality is an approach, which can be applied in any other locations.
